It's the worst when it fluxtuates in shots too. Balls for 10 seconds, girls face for 20 seconds. Turned off, turned on. I end up just staring at the ceiling playing the picture of what I want to see in my head.

You are more patient than I am. I get somewhat aggressive and angry when it happens. I usually end up finishing on a blowjob video because it never happens on them, except when they film the guy's face, but it is never for too long.
